Be it known that I, EDWIN F. PORTER, a subject of the Queen of Great Britain, residing at Boston, in the county of Suffolk and State'of Massachusetts, have iHVGHtQd COF tain new and useful Improvements iii-Apparatus for Heating and Agitating Air, of which the following is a specification.

Jyiuveution relates to improvements in apparatus for heating and agitating air; and its object is to thoroughly heat antidistribute a body of air throughout an apartment.

In carrying out my invention I use a fan,

b'rin heated 'air and products of combustion in contact with blades, from which it is thrown into the apartment, the air being first heated by oil 'orgas jets placed below the hood. By incans'of this device a large body of air is more rapidly and thoroughly heated and dif- Sible with any present style of stationary gas- -radiator or gas-log, which imparts its heat to the air coming in contact therewith byordinary slow circulation.

'My invention consists of certaiu novel features hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying myinveution, Figure I is a side elevation, partly broken away to show the gas or oil jets. Fig. 2 is a front elevation. Fig. 3 is a rear view with the hood partly broken away and showing the fan and motor for runningthefan. Fig. 4is aside view in section, showing the construction of the motor..

Like letters of reference refer to like parts throughout the-several views.

To a suitable base A there is secured a hood l3, and in the bottom of said hood thereis ar-' 1 mged a series of oil or gas jets G, which heat the air entering through the openings 0 in the hood 13. Through an opening Din the hood B the shaft E passes and is operated by means of a suitablo'motor F, resting on the support G. On the frontend of said shaftE there is arranged a'fan H, fast on the shaft E and having a series of blades H. The air on.- ters at the apertures C and, beiagheated by.

motion from thefpistom 0 is imparted the burner, rises and circulates against the fan H, which fan, being revolved by the mo-" tor F, throws the heated air and products of combustion 01f into the apartment and by its exhaust action accelerates thed'raft through the apertures 0, thereby heating a greater amount of air .than would be heated by'the 3 ordinary circulation, as is the case with the present style of gas-radiators.

- In Figs. 3 and 4 is shown a specially designed motor'for operating the fan, and this motor consists of an expansioh-chamber K, inclosing'a displacer-L, which is a solid cyl inder of any desirable materialand, is operated by the lever M, working in the slot M in the displacer L, and the lever M in turn is operated by the link N, pivoted to the piston O, which operates inth'ejcylinder P. The to the fan H throughthe-piston-rod Q, connected to the crank R on the shaft S, which is supported by the beams T. The shaft continues through thehood B, and to it is secured the tan H, which is revolved by the-rise and fall of the piston. O. The to'and-fro movement of the lever M, pivoted at M is caused by the contact at the upper end of the lever M of the nuts M and M. The expansionchamber K extends into the hood Band is heated by the burner 0, thereby in this device'ntilizing the heating-flame for running the motor and for heating the room. The body of air K, being first heated in the end of the chamber K, located over the burner C,-is

forced by he movement of the displacer L,

owing to the expansion of air in the chamber K, against the under side of the piston 0 into the opposite or cool end of the chamber K, (shown in Fig. 4,) where it contracts, causing atmospheric pressure to depress the piston O,

and the piston O descending forces the lever M backward, throwing the displacer L to the outer end of the chamber-K, which forces the body of air K to the inner end of the chamber K through'the space around the displace:-

I5, which works looselv in the chamber Knn" the ball-bearings 1c. "The body of air'K being now in the inner heated end ofthe'chamber K is expanded, forcing the piston 0 upward, thereby completing the revolution of desire to secure by Letters the shaft S by the movement of the piston O,

and this m'otion is repeated while the burner O is in operation. In this arrangement, as in Figs.) a'nd'f2' therein entering the hood B is heatedand rises 'and is distributed with the prodnetsieiscombnstion throughout the room by the-motion of the fan H.

In apparatuses where the fan or equivalent device is operated solely by the current of heated air and products of combustion the force of the currentand the force of the motor arethe same, and in practice the operation of the motorby,such--'current would be retarded owing to the friction of the parts, for the apparatus to be effective and tofpr'o-' d-uce a lateral-diffusion of the heated air and products of combustion the motor operating the fan must have a greater potential than "the draft or ascending current of heated air andproducts of combustion in order that the" current of heated air and products of combustion may be accelerated andrapidly' d-if-' fused throughout the apartment I do. not limit myself to the arrangement and constructionshown, as the same may be variedwithout departing from the's'pirit of my invention. W gI-Iaving thusascertained the nature of my invention and set forth a-construction em bodying the same, what I claim as new', and
